1 When finding unknown values, plug what you know into the formula and solve for what’s missing! Find the height of the triangular prism.V = AhA = Area of the baseh = height of the solidAtriangle = bh1212Volume = ( bh)hh12189 = (7)h7 m6 mThe volume of the prism is 189 m3.

2 The height of the prism is 9 meters!!V = AhA = Area of the baseh = height of the solidAtriangle = bh1212189 = (7)hPlug in what you know.12189 = (42)h6(7) = 42h12189 = 21h(42) = 217 m9 = hDivide both sides by 21.6 mThe volume of the prism is 189 m3.The height of the prism is 9 meters!!

3 V = AhA = Area of the baseh = height of the solidThe volume of the prism is 264 in3. The height is 22 in. Find the area of the base.Atriangle = bh12Don’t be mislead by how the solid sits. A triangle needs to be the base.If necessary, ROTATE IT!

4 The area of the triangular base is 12 inches!!V = AhA = Area of the baseh = height of the solidThe volume of the prism is 264 in3. The height is 22 in. Find the area of the base.Atriangle = bh12264 = A22Plug in what you know.2212 = ADivide both sides by 22.The area of the triangular base is 12 inches!!
